Answer:
The advantage for the above condition is as follows:-
Explanation:
- If a user creates a defined constant variable and assigns a value on its and then uses that variable instead of the value, then it will a great advantage.
- It is because when there is a needs to change the value of that variable, then it can be done when the user changes the value in one place. There is no needs to change the vale in multiple places.
- But if there is a value in multiple places instead of a variable and there is no constant variable, then the user needs to change the value in multiple places.
Answer:
Encapsulation:-It is the binding of the data and functions so that they works as one unit.
Inheritance:-When one class acquires the property of another class it is called inheritance.
Polymorphism :-It generally means more than one form
Explanation:
Encapsulation:- class is an example of encapsulation it can hold different data types and functions in a single container called class.
class Name{
public:
string first_name;
string last_name;
void Display()
{
cout<<first_name<<" "<<last_name<<endl;
}
};
Inheritance:-The property of a class acquiring the properties of another class is called inheritance.
Now we will inherit the above defined class.
class person: public Name
{
public:
char gender;
int age;
void Display()
{
cout<<first_name<<" "<<last_name<<gender<<age<<endl;
}
};
int main()
{
Name n;
person p;
n.Display();
p.Display();
}
Polymorphism- There are two types of polymorphism:-
1.Run time polymorphism=The values are decided at run time.
2.Compile time polymorphism=The values are decided at compile time.
Example:-In the above example we have function Display() in both the classes.This is an example of compile-time polymorphism. We are deciding at the time of compilation which display to use.
Answer:
volume mount points
Explanation:
The best thing to do would be to use volume mount points. This is a feature that allows you to mount/target (from a single partition) another folder or storage disk that is connected to the system. This will easily allow the user in this scenario to access the different files located in the D: and E: drive from the C:\ drive itself. Without having to go and find each file in their own separate physical drive on the computer.
